FujiClean Jokaso Pilot Project
Japanese wastewater treatment technology for use in cold climates and rural communities
In August 2025, the FujiClean Jokaso pilot launched at ACWA. The project team is evaluating the FujiClean Jokaso unit for use in cold climates, to assess if the technology can be used in rural communities, instead of septic tanks or lagoon systems.
This is the first project under a Memorandum of Understanding between UCalgary and Japan Sewage Works Agency. Through this collaboration, our institutions can test and improve technologies, share best practices, and develop new knowledge, for the benefit of communities in Japan and Canada.
This project is a partnership between UCalgary, Japan Sewage Works Agency, FujiClean and LM Wastewater, with support from Alberta Innovates.
How does it work?
The Jokaso operates with the same biological processes used in municipal wastewater treatment. Wastewater moves through five chambers, where solids are broken down and disposed of, and the water is treated via filtration, clarification, and disinfection. The resulting effluent is clean enough to safely re-enter water sources.
If the pilot is successful, the Jokaso unit could improve quality of life for small and remote communities by providing access to simple technology that works better than existing systems. It has the potential to advance best practices for source water protection and water treatment in Alberta and across Canada.
